Putting an error in pins_duino1284.cxx did indeed cause an error, so the file would seem to be seen.

You know, Think I just noticed something that might help.In pins_duino1284.cxx, there are 6 arrays.I didn't change the first 3, just the second 3.I just noticed that the pin assignments seem to follow the first 3 arrays, and not the last 3.

Success!!To make it work, I stripped out the pins_arduino.c file in the arduino-0022 folders area and changed it to the listing below.

I renamed the pins_arduino.c in the arduino-extras folders area to a name that didn't start with pins.

If there is a way to make the #ifdef's work for other processors, I'd like some direction on making that work.For now, I am only compiling correctly for "my" 1284 and have to revert to naming files to use '328 Duemilanoves.!

Yeah, when it works! I am 100% confident in the hardware, getting the software to play nice is the tricky part.Since I unique-a-fied my pins_arduino.c file for just this board, I have some fooling around to do now to use my '328 boards.

Anyway, back to an RTC sketch.Tomorrow, I guess, contacts are getting pretty dry ...

Thanks mnmis.This section (actually the 2 above it, but the end results are obvious in this one) show the resulting pin mapping from PA-1 ... PD-7 to the D0-D31 that show up on the actual IO. My board uses them somewhat differently.I will modify this to reflect mine & check it out. I had the hardest time getting this info pulled in by the IDE, finally resorting to removing everything but my 1284 needs.

If I had understood how this worked when I was assigning pin usage on the board, I may have assigned pin usage differently.As it was, I tried to match pin usages to reflect the Duemilanove pin usage on shield headers for maximum compatibility.
